Common Problems
The following symptoms are not a malfunction, and in most situations will not require repairs.
Problem Possible Causes
Unit does not
turn on when
pressing ON/
OFF button
The unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of being
turned off.
Cooling and Heating Models: If the Operation Light and PRE-DEF (pre-heating/
defrost) indicators are lit up, the outdoor temperature is too cold, and the unit’s
anti-cold wind feature is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in
order to defrost the unit.
The unit changes
from COOL mode
to FAN mode
The unit changes its setting to prevent frost from forming onto the unit. Once
the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns off the
compressor. The unit will resume operating when the temperature fluctuates
again.
The indoor unit
emits white mist
In humid regions, a large temperature difference between the room’s air and the
conditioned air can cause white mist.
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
The indoor unit
makes noises
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode, due to
expansion and contraction of the unit’s plastic parts.
Both the indoor
unit and outdoor
unit make noises
A low hissing sound may occur during operation. This is normal and is caused by
refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard when the system starts, has just stopped
running, or is defrosting. This noise is normal, and is caused by the refrigerant
gas stopping, or changing direction.
The outdoor unit
makes noises
The unit will make different sounds based on its current operating mode.

Troubleshooting
Problem Possible Causes
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use, which will be
emitted when the unit is turned on. This can be mitigated by covering the unit
during long periods of inactivity.
The unit emits a
foul odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.), which will be emitted during operations.
The unit’s filters have become moldy, and should be cleaned.
